and useful Improvements in .Valve-Mech-.

anism, of which the following is a specification.

This invention relates to improvements in valve mechanism for power pumps, motors and the like. v

The object of the invention is to make more certain and effective the operation of valves for devices of this character.

The invention consists in the construction and combination of parts hereinafter described and set forth in the claims.

In the accompanying drawings: Figure 1 is a side elevation of a device embodying the invention. Fig. 2 is a vertical section through the cylinder and valve'casing of the same. Fig. 3 is a vertical section of one of the valves and its connected parts. Fig. 4 is a bottom plan view of the same.

Like parts are represented by like characters of reference in the several views.

The device to which I have shown my improvements applied in the drawings is a horizontal water power pump, although, as before stated, the improvements are applicable to valves employed in other structures, such, for instance, as water or steam motors.

In said drawings, 1 represents the cylinder proper and 2 the piston, operated, in the device shown in the drawings, from any suitable source of power applied to the rod 3.

4 is the valve casing, formed integrally with the cylinder in the usual way and having an inlet chamber 5, a discharge chamber 6 and intermediate chambers 7 and 8 arranged in a usual and well known way. The intermediate chambers communicate with the respective ends of the cylinder by ports 9 and 10 and with the respective inlet and discharge chambers by ports 11, 12, 13

' and 14:. The inlet chamber has the usual intake 15 and the discharge chamber the usual outlet 16.

The valve which I have employed and to which my improvements more particularly relate is that of the well known lifting or puppet type and one of these valves, a, b, c, d, is employed in each of the ports 11,12, 13 and 14 previously described. Inasmuch as the main improvements which I have devised are common to each of the valves, a description of one will be sufficient.

17 represents the valve proper which has an upwardly projecting stem 18. Connected to the bottom face of the valve 17 is a series of guides. 19, preferably four in number, although any suitablenumber may be employed. The outer faces of these guides 19 are preferably rounded asshown in Fig. 1

and the guldes are so arranged as to snugly but loosely fit in the port with which they are associated. These guides 19 are connected integrally with a central web 20 and are secured to the valve proper by a screw 21, or other suitable fastening device, which passes through the'web and is screwed into the body of the valve and its stem; a packing or washer 22 of suitable material being interposed between the web and face of the valve proper. To prevent the guides and their web from turning with respect tothe valve proper, I have provided small lugs 23 formed integrally on the valve proper which extend through the washer 22 and into recesses in the web 20.

It will be observed that the valve, a, is arranged directly in line with the valve Z) and is the larger of the two and also that the valve 0 is likewise arranged and proportioned with respect to the valve (Z. When the valves are assembled it will be seen that the stem 18 of the valve 6 will fit within the guides 19 of the valve a and that the stem of the valve, d, likewise fits within the guides of the valve 0. It will also be seen that the stems 18 of the respective valves a and c are fitted within guides 24 formed integrally with the usual screw-threaded plugs 25 which are employed to close the openings in the valve casing through which the valves are inserted and through which access may be obtained thereto.

By this construction it will be seen that the respective valves will be guided in their lifting and falling movement and will be held in perfect alinement with the ports so that the tendency to jam or stick by reason of the tilting of the same is obviated. It will also be seen that by having the guides on the respective valves and caps spaced apart, the water will be permitted to escape between the guides when one of the valves lifts so that there will be no interference with the action of the valves.

Having thus described my invention, I claim:

1. In a device of the character described,

a plurality of valves arranged in vertical.

alinement with each other, a series of circularly arranged downwardly projecting guides on the lower side of the upper valve, said guides being spaced apart so as to form a socket with openings in its walls, an upwardly extending stem on the lower valve projecting into said open socket, and guides on the lower side of said lower valve.

2. In a device of the character described, a valve formed in two parts, one of said parts having guiding projections and the other of said parts a guiding stem, a washer between said parts, and means for securing the said parts together and also against rostem of the upper valve, said casing guides being also spaced apart so as to form a socket with openings in its walls.

In testimony whereof, I have hereunto set my hand this 14th day of January 1911.
